To expand the physical memory address space, which of the following is used?
Virtual Memory
Removable Drives
Memory Cache
Hard Drive
Virtual memory is used to increase the size of available memory for programs to execute and load.
Virtual Memory Most OS’s have the ability to simulate having more main memory than is physically available in the system. This is done by storing part of the data on secondary storage, such as a disk. This can be considered a virtual page. If the data requested by the system is not currently in main memory, a page fault is taken. This condition triggers the OS handler. If the virtual address is a valid one, the OS will locate the physical page, put the right information in that page, update the translation table, and then try the request again. Some other page might be swapped out to make room. Each process may have its own separate virtual address space along with its own mappings and protections.
